Logos just seems sluggish on my computer since upgrading to L6 core engine. I get a lot of "not responding" messages at the top of the screen or there is just a general lag in how it functions. It almost never actually crashes though. Lately my cpu is running at 25% or so and logos is running but it is just open and sitting there with a passage guide open etc but I am away from my desk and have not asked it to do anything. I am trying to attach my log files but it keeps getting stuck so I will try to add those again later. I hope someone can see if there is anything I can do. It does not do this all the time. It just seems like it gets stuck. I am running a Dell Vostro 3750 with 4 GB RAM, an I5 processor, and Windows 64 bit professional if any of that matters. I have L4 Platinum with L5 crossgrade now running on the L6 engine. Thanks
